Re: [Users] failover and presence/IM service

Hello, On 06/21/05 13:34, jimmy way wrote: there is a module named "dispatcher" that can be used to distribute the traffic. It does static distribution, does not count the load of a server. There is no exlicit support for hot backup in openser/ser. You have to use third-party products to be able to switch between the active and backup servers. The two servers can be kept synchronized using t_replicate(). No, it does not support Jabber/XMPP, just SIP and SIMPLE. It includes a Jabber-to-SIMPLE gateway which is able to translate from a protocol to another. The presence does not work, because presence support in openser/ser (pa module) in under heavy development and not released as stable. Also, the jabber module (the Jabber-to-SIMPLE gateway) was not tested with latest Jabber servers. I have started long time ago to write a pure SIMPLE-to-XMPP gateway which will allow on-the-fly gatewaying, without authentication as it is now (the authentication is required so users can provide ICQ/MSN/AIM accounts to get from SIMPLE to that IM network via Jaber). If someone wants to take over, I can give some help at the beginning. Jabber is also a bit older than SIMPLE and it was designed for instant messaging and presence. SIMPLE is just an extension for SIP to enable instant messaging and presence, so it carries the design of VoIP. OpenSER can interwork with any SIP-compliant entity With VoIP gaining more and more supporters, SIMPLE may be a winning card, but I think will take some time to have mature implementations at least for presence. As I see things evolving at IETF, the format to carry presence information is going to be unified (if not yet) and SIP/SIMPLE or XMPP will be carrier protocols. Also, XMPP started to develop extensions for VoIP :) ... Regards, Daniel
